The K.I.S.S. Principle: OS Not Required™
There are times when a Linux or embedded RTOS are called for, but there are times when a project needs a PC file system without the increased complexity of an OS. By embedding a complete FAT file system on low cost and power efficient silicon along with the physical card interface, adding gigabytes of file storage becomes simplified.

Total System Cost
When engineering a project, silicon typically gets the most attention. However, digital hardware design always sits in an analog world, and the supporting passive components for each silicon IC add up in terms of larger BOMs, i.e., more procurement efforts, increased PCB real estate, and with volume: cost. The DOSonCHIP silicon has been designed to minimize the external supporting components. In fact, the simplest configuration requires only 2 common external capacitors and the socket for the memory card (optional date & time clock requires watch crystal plus 3 passives).

Application Examples:
● Data Logging
One of the main requirements for data logging is extremely low power consumption. Low power is often required to extend battery life or to leverage a micropower supply. The engineer needs to look at both the active and sleep power consumption over the time needed to make sure the project meets its design goals. The DOSonCHIP IC has been designed to keep power at a minimum when operating and when asleep.

● FPGA Configuration
Does your design include a large gate FPGA? How about multiple FPGAs? Would you like to reconfigure your design in the field, or load different FPGA profiles on user demand?
By adding DOSonCHIP silicon to your design, you can easily download multiple configuration files to the SD card from your PC, plug it into your design, and select which one should be loaded into your FPGAs. In addition, you can store additional data on the card as needed by your design.

● Web Server
There are many embedded web server solutions available today. However, most solutions either have limited flash storage, or cumbersome methods to update the web files. By adding DOSonCHIP silicon to your web server solution, you can easily transfer gigabytes of web server files from your PC to an SD card and plug it into your embedded server. If your server adds files, they can also be backed up to the PC at a later time.
